Specification of Letters Patent.

Patented Feb. 21, 1922.

Application filed January 12, 1920. Serial No. 850,803.

To all whom it may concern."

Be it known that I, CARL HERRMANN ROTH, a sub ect of the King of Great Britain and Ireland, residing at Southport,

in the county of Lancaster, England, have invented certain new and useful Improvements in Carpet Sweepers, of which the following is a specification.

This invention relates to apparatus for collecting and removing dust, dirt, and other refuse from carpets, chairs, cushions, and is equally applicable for the washing and polishing of floors and other surfaces, and also for brushing upcrumbs from tables and the like.

The main features of the invention consist in providing a sweeper with a loosely fitting removable lid, and one or more spring washers whereby the handlc'may be held upright, when the machine is not in use, and also in which there is an entire absence of springs or clips for opening and closing of the dust pans.

The invention will be better understood by aid of the accompanyingdrawings in which Figure 1 is an end elevation, Figure 2 a cross section, Figure 3 a partial bottom plan view, and Figure 4 a detail view of the spring washer.

In these 1 is the body or receptacle of any suitable size and shape, having a loosely fitting top or cover 2 completely covering the brush and dust pans. 3 are rollers on which said receptacle is mounted. 4 is a brush the ends of which engage in slots or grooves in the body, and are driven by said rollers 3 which atter are mounted on the axles 5 and supported in slots (5 in the ends of the receptacle 1. 7 are trays of any suitable resilient material such as tinplate, or thin steel sheet, or springy material, and form the base of the receptaolev 1, the sides of the trays being firmly connected to receptacle 1 and to the axles 5 of the rollers 3 respectively. By thus mounting the trays 7' great resiliency of the machine is obtained, and the inner edges of said trays always remain the same distance from the carpet or surface over which the machine passes when in use. These trays 7 are preferably rounded or curved from the side towards the centre of the body, the inner sides of the said trays 7 at each side of the brush 4 being turned or bent upwards in the form of a ridge or rim as shown in the drawings, so as to prevent the dust when collected from falling out therefrom. S is a rod extending across each end of the body and is arranged preferably somewhat above the centre of the rollers .3. This bar 8 is provided with slots adapted to allow pins or studs 10 on the ends of the handle bar 11 of the handle 12 to pass through and into the ends of the brush 4, and on which pins 10 the said brush rotates. 13 is a projection of flat resilient material arranged at either or both ends of the receptacle 1 and extends somewhat beyond the rollers 3 as seen in' F igure3 and against which projection the handle bar 11, on being raised, is pressed and retained in an upright position when the machine is not in use. In Figure -i there is illustrated a handle positioning device which may supplement the member 13 or which may be used independently thereof. This device is a helical spring l i fixed at its ends to the members 8 and 11 and operative to normally hold the handle upright. To enable the brush 4 to be readily removed, the pins 10 on handle bar 11 are withdrawn from the brush by simply pulling the ends of the latter outwards from either end of the machine.

The mode of action is as follows The sweeper on being passed over the floor or surface causes the rollers 3 and brush l to rotate, and according to the pressure ap' plied by the handle 12 the body and brush will move vertically in the slots of the body and the machine pressed more or less to the surface. The removal of the dust collected in the trays 7 is effected by simply removing the cover 2 and the dust is extracted either by hand or the receptacle can be turned com pletely over on the pivots 10 and the dust or dirt allowed to fall out through the opening at the top. The cover 2 can then be replaced and the machine is again ready for use. As before stated the brush can be re moved by simply withdrawing the pins 10 on the handle bar 11. When the machine is not required for use the handle bar 11 is raised so that one or both of its sides presses against the projection 13 or washer let and thus holds the handle 12 in an upright position.

The handle bar 11 may also be mounted directly on the bar 8, and be secured in position by any suitable means such as nuts and bolts.

The washer 14 may be arranged between the handle bar 11 and bar 8, or'between the handle bar 11 and the body 1, in cases where the said handle bar is pivoted directly to the body as an additional or alternative means for retaining the handle 1:2 in an up- 7 right positionwhen the machine is not in use. 7

By means of my invention it will be seen that a sweeper made in accordance therewith is very simple in construction, cheap to manufacture, and in \vhichthere is an entire absence of springs or clips for operating the opening and closing of the dust pan,

and by means of the removable lid or cover,

the removal of the dirt collected is more easily accomplished and without any risk that I claim is,:

1. In a carpet sweeper, a receptacle, supporting rollers and axles therefor vertically movable relative to the receptacle, a dust pan forming the base of the receptacle and affording resilient support for an axle and a brush in the receptacle driven by said rollers. i

2. .In a carpet sweeper, a receptacle, supporting rollers and axles for said receptacle, the receptacle beingrvertically movable relative to the rollers and axles and to a surface operated upon, and dust pans connected between the receptacle and the axles resiliently supporting the edges of the receptacle,

the lowermost portions of thepans being substantially vertically beneath the axles whereby the lowermost portions of the pans are supported "a fixed distance above the surface operated 011 irrespective of vertical movement of the receptacle Signed at Liverpool in the county of Lancaster this l7t-l1 day of December 1919.
